textured polyester for the pile, overlapping the points and laying-in on the needle
bar.
Using an eight-link-per-course cycle, the overlap for the points occurs between
the first two links, the overlap for the pillar stitches on the needle bar occurs between
the second two links, whilst the last four links allow the points and needles to
descend for knock-over and for the underlap inlay on the back bar.
An unusual use is three guide bar structure for the artificial turf,
Astro-turf
[6],
whose pile is composed of four, six or eight ends of 500 denier dope-dyed nylon
ribbon on a nylon polyester knitted and inlaid base fabric.
